I am suggesting a language change in the default install when someone registers and registration verification is set to email (or others with the similar message) that it be changed to read the following.
When the user has a free email client such as MSN hotmail, lycos, yahoo or other provider of the kind, sometimes you get the email in 1 min, sometimes its 10 min, and sometimes its an hour. So i think this is a simple change to make, in order to provide better information to the user on the front side.'ACCOUNT_INACTIVE' => 'Your account has been created. However, this board requires account activation. A activation key has been sent to the email address you provided. Please check your email for further information. Be sure to check your junk mail box. It may take up to 1 hour to get the email depending on your email providers server loads.',
